Assessing the Accurate Topography of Complex Channeling Corrosion

This white paper presents a case study of an offshore pipeline with pittingLocalized corrosion of a pipeline's metal surface, resulting in small, localized pits or cavities. and long axial corrosionThe deterioration or degradation of a pipeline caused by chemical or electrochemical reactions with its environment.
